i have a manual 1987 325is and it seems to be shifting kinda hard compared to my friends 88' 325i. it has been doing it ever since i got the car but i never worried about it until i drove her car wich shifts as smooth as butter compared to mine. both cars are stock. the shifter feels like it gets hung up or something. i also noticed it gets worse in cold weather... at least until the car warms up. could it be tranny fluid????
